Recombinant human Kallikrein 11/KLK11 protein

KLK11, also known as kallikrein-11 isoform 1, is belongs to the peptidases S1 family and Kallikrein subfamily. It is expressed in many tissues including cerebellum, prostate, salivary glands, stomach, lung, thymus, small intestine, spleen, liver, and uterus. These expression appear to be regulated by steroid hormones in the breast carcinoma cell line BT-474. Based on it serum levels, this protein has been proposed that ovarian cancer cases can be distinguished from healthy controls, who display very low expression. Also, it that is activated by thermolysin is active against thioester substrates such as dichloroisocoumarin and aprotinin. Recombinant human KLK11, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
